To enable in-place editing of text of diagram items, set the AllowInplaceEdit property to true. It lets users edit the text of a diagram element by double-clicking it. In-place editing mode can be accepted and exited by clicking anywhere outside the text-field.
The following properties can be edited in place:
If you want to change the way of accepting / rejecting changes, the following Diagram properties allow using the ENTER and ESC keys to perform that: InplaceEditAcceptOnEnter and InplaceEditCancelOnEsc. When InplaceEditAcceptOnEnter is set to true, pressing the ENTER key causes accepting changes and exiting inplace-edit mode. If InplaceEditAcceptOnEnter is set to false, pressing ENTER inserts a new line in the text while in inplace-edit mode. If InplaceEditCancelOnEsc is set to true, pressing the ESC key performs rejecting changes and exiting inplace-edit mode.
If you want to enable/disable in-place editing of a specific table's cell, handle the CellTextEditing event. To enable/disable in-place editing of nodes, handle the NodeTextEditing event. For a DiagramLink object, the LinkTextEditing event is raised while in-place editing. These validation events let you prevent users from editing the text in the particular object if it is necessary.
When in-place editing of a node is completed, the NodeTextEdited event is raised. For a table's cell, handle the CellTextEdited event. LinkTextEdited event is raised when in-place editing of a DiagramLink object completes.
By default, Diagramming for WPF creates a TextBox control to let users edit item's text. The EnterInplaceEditMode event allows customizing the properties of that control, or attaching event handlers to it. InplaceEditFont specifies the font of the in-place edited text box.
When leaving inplace-edit mode, the LeaveInplaceEditMode event is raised. This event is raised in all cases of closing the inplace-edit control, for example, when the user accepts or cancels the changes made to an item's text, or when the EndEdit method is called.
To enter in-place editing mode programmatically and let users edit an item's text inline, call the BeginEdit method of DiagramView. The EndEdit method exits inplace edit mode.
GetEditRect returns the destination rectangle of the in-place edit box. GetTextToEdit represents the initial contents of the in-place edit box. SetEditedText sets the edited text to the object after completing the in-place editing.
